Description

The invention relates to the field of food industry, in particular to the dairy and oil and fat industry, and in particular to a method for the production of butter.

A known method for the production of butter, consisting in the fact that the oil-fat emulsion is processed in a cylindrical scraper heat exchanger with intermediate processing in a rotary homogenizer in three stages. At the first stage, the oil-fat emulsion is cooled in a cylindrical scraper heat exchanger to 15-25 ° C with a specific power of mechanical processing of 70-88 W / kg for 60-102 s. In the second stage, the oil-fat emulsion is converted into a reverse-type dispersion in a rotary homogenizer with a specific mechanical power of 5000-7500 W / kg for 2-4 s. In the third stage, the product is cooled at 3-9 ° C at a specific power of machining of 230-300 W / kg, and then packaged by pouring in a rigid container or molded into briquettes on packaging machines [Ukrainian patent No. 55510, A 23 C 15/06 , 2000].

This method does not allow to obtain a sufficiently plastic consistency of the product at refrigerated storage temperatures (0-5 ° C), which reduces its consumer properties. The reason for such features of the rheological properties of the product is an increase in temperature during intensive machining in a rotary homogenizer and insufficient mechanical processing of the product in the second and third stages of the process. In the second stage of the process, with increasing temperature of the product, its viscosity decreases and, therefore, the stability of the dispersion decreases, which leads to the fusion of particles of the aqueous phase. In the third stage, the insufficient duration of machining with continuous stirring leads to an increase in the proportion of "hard" crystalline bonds formed in the product in a static state (after packaging).

The basis of the invention is the task of creating a method that allows you to get butter with improved consistency by optimizing the thermomechanical processing of the product in the apparatus.

The problem is achieved in that in a method for the production of butter, comprising the first stage of cooling high-fat cream in the cooling cylinder of the scraper heat exchanger, the second stage of the conversion of high-fat cream into an inverse dispersion, the third stage of cooling and formation of the primary structure of the product before packaging, according to the invention, the first stage, high-fat cream is cooled to a temperature of 25-35 ° C for 110-190 s with a specific power of mechanical processing of 90-170 W / kg, in the second stage for a phase reversal and dispersion of a fat emulsion, the product is cooled to 12-18 ° C for 55-155 s with a specific machining power of 130-370 W / kg and a rotation speed of the mixing device inside the cylinder of 200-500 rpm, obtaining a water / fat type dispersion; in the third stage, in the processing cylinder of the scraper heat exchanger to form the primary structure, the product is cooled to 7-18 ° C for 175-250 s with a specific machining power of 80-310 W / kg and a rotation speed of the mixing device The properties inside the processing cylinder are 50-300 rpm.

A good consistency of the product is ensured by the fact that in the second stage of the process, the stability of the resulting water / fat inverse dispersion is increased by cooling the product and increasing its viscosity, which helps to prevent subsequent undesired moisture particles from interconnecting. At the third stage of the process, when the primary structure of the product is formed, a part of the fat phase (capable of hardening at temperatures above 0 ° С) is more completely crystallized due to an increase in the cooling time of the product, while the product is continuously mixed in order to break down the crystallization bonds between the hardened fat particles . This allows you to achieve a finer distribution of moisture in the product and the formation of an increased proportion of easily restored coagulation bonds between crystalline fat particles that make up the backbone of the product. Together, this provides a more plastic consistency of the product at storage temperatures in domestic refrigerators. Heat removal in the second stage of the process with intensive simultaneous mechanical processing of the product is carried out using heat transfer cylinders with an increased rotation speed of the mixing device, and the duration of the mechanical processing is increased by using special mixing devices with an increased product gap. The proposed method allows to obtain a product with improved consumer properties and eliminate the defects of consistency at refrigerated storage temperatures.

The invention is illustrated in the drawing, which depicts an oil former.

The oil-forming votator contains a cooling 1 cylinder connected to a cylinder 2 of a scraper heat exchanger for phase reversal and dispersion of the fat emulsion connected to the processing 3 cylinder.

A method of producing butter is as follows.

High-fat cream is fed into the cooling cylinder 1 of the scraper heat exchanger, where they are cooled through a heat exchange surface with the help of a refrigerant to a temperature of 25-35 ° C for 110-190 s with a specific machining power of 90-170 W / kg. Inside the cooling cylinder, the product is mixed using a mixing device with scrapers (not shown), rotating inside it with a rotation speed of 100-200 rpm.

* Then, the fat / water type fat dispersion is fed into the cylinder 2 of the scraper heat exchanger for phase reversal and dispersion of the fat emulsion, where it is converted to the water / fat type inverse dispersion by intensive machining and cooling to 12-18 ° C for 55-155 s at a specific power of machining of 130-370 W / kg. The increased rotation speed of 200-500 rpm of the mixing device with scrapers allows creating conditions for phase reversal while cooling the product. The heat generated during intensive machining is removed using a heat exchange jacket located around the cylinder.

After this, the product is fed into the processing cylinder 3 of the scraper heat exchanger to form the primary structure, where it is subjected to additional thermomechanical treatment while cooling the product to 7-18 ° C for 175-250 s with a specific machining power of 80-310 W / kg. The rotation speed of the mixing device of the processing 3 cylinder scraper heat exchanger is 50-300 rpm The duration of the machining of the product is increased by increasing the volume filled by the product in the processing cylinder. In this case, stagnant zones are not formed in which mechanical processing of the product would not occur, which prevents the formation of solid grains in the product. Thus, the primary structure of the product is formed before its packaging.

The method is illustrated by examples.
